Characteristic, features and application areas of Orbital Motors

Danfoss is a world leader within production of low speed orbital motors with high torque. We can offermore than 3000 different orbital motors, categorised in types, variants and sizes (incl. different shaftversions).

The motors vary in size (rated displacement) from 8 cm³ [0.50 in³] to 800 cm³ [48.9 in³] per revolution.

Speeds range up to approx. 2500 min-1 (rpm) for the smallest type and up to approx. 600 min-1 (rpm) forthe largest type.

Maximum operating torques vary from 13 N•m [115 lbf•in] to 2700 N•m [24.000 lbf•in] (peak) andmaximum outputs are from 2.0 kW [2.7 hp] to 70 kW [95 hp].

Characteristic features of Danfoss Orbital Motors

• Smooth running over the entire speed range

• Constant operating torque over a wide speed range

• High starting torque

• High return pressure without the use of drain line (High pressure shaft seal)

• High efficiency

• Long life under extreme operating conditions

• Robust and compact design

• High radial and axial bearing capacity

• For applications in both open and closed loop hydraulic systems

• Suitable for a wide variety of hydraulics fluids

Technical features of Danfoss Orbital Motor

The programme is characterised by technical features appealing to a large number of applications and apart of the programme is characterised by motors that can be adapted to a given application. Adaptionscomprise the following variants among others:

Introduction

By introducing the VMP, Danfoss is introducing an Orbital Motor in the new V-Series. In order to meet thedemands for motors that have the right duty cycle and efficiency capabilities for a given function,Danfoss now has 3 Orbital Motor Series:

T-Series – The Highest Torque

Leading performance with a long lifetime makes light work of the heaviest duties. Offering pressurecapability up to 350 bar [5076 psi] and high starting torque, the T-Series is the energy-efficient choice forthe toughest working environments.

O-Series – The Flexible Choice

The O-Series is flexible beyond compare. Delivering premium power across the board, these motorscover small to large, medium to heavy-duty needs with pressure capability up to 275 bar [3990 psi].Robust, reliable and designed to fulfill the latest emissions standards.

V-Series – The Core Solution

The V-Series is your quality benchmark in the medium duty market. Based on proven technology, thesereliable motors will reduce your overall system costs while adding value to your machine. Perfect formany tasks.

VMP features

• High pressure shaft seal• Proven orbital motor design• 3-chamber motor design• Suitable for medium and low duty

Speed, torque and output

The bar diagrams, are useful for a quick selection of relevant motor size for the application. The finalmotor size can be determined by using the function diagram.

The function diagrams are based on actual tests on a representative number of motors from ourproduction. The diagrams apply to a return pressure between 5 and 10 bar [75 and 150 psi] when usingmineral based hydraulic oil with a viscosity of 35 mm²/s [165 SUS] and a temperature of 50°C [120°F]. Forfurther explanation concerning how to read and use the function diagrams, please consult the paragraph"Selection of motor size" in the technical information "General" 520L0232.
